APPARATUS FOR TREATING HYDROCARBONS.

Application filed July 23, 1920, Serial No. 398,421. Renewed September. 2, 1926.

This invention relates to improvements in apparatus for treating hydrocarbons and refers more particularly to an apparatus which, if desired, can be utilized for cracking petroleum oils.

Among the objects of the invention are to provide a. construction in which the heating element is preferably surrounded by and extends through the still and in which both the heating element and still or part of the latter are constantly rotated whereby not only a more uniform heating of the oil is obtained but to a pronounced degree there is less tendency for the i recipitated carbon to deposit upon the heating element which is the hottest part of the apparatus; to provide a construction of the above character in which the heating element and the movable still member preferably rotate in opposits directions so as to more effectively obtain the preceding object; and in general to provide an improved construction'of the character referred to.

In the drawings,

' l ig. 1 is a view partly in side elevation and partly in vertical section of our improved construction showing more particularly the. .still and heating element and certain connections.

Fig. 2 is an enlarged detail view of the joint between stationary and movable parts of the still shown at X in Fig. 1.

Fig. 3 is an enlarged sectional detail view ofthe joint between the still and heating element shown at Y in Fig. 1.

Fig. 4 is a transverse sectional view taken through lines A-A of Fig. 1. I

Fig. 5 is an assembled view of the ap paratus as equipped for cracking oil.

Referring to the drawings, 1 designates as a whole a still comprising the stationary portion 2 and movable portion 3. Stationary portion 2 is mounted upon suitable support at and the movable portioniupon supports 5 and 6. The two portions of the still are connectedby tongue and grove joint 7 comprising the movable part 8 and stationary part 9 connected to the movable and stationary parts of the still respectively. The movable portion 3 of the still is provided with ciroumferentially extending gears 10 and 11 which mesh with the pinions l2 and 13. The inions 12 and 13 are driven by shafts let an drive pulleys 15 connected to any suitable source of motive power (not shown).

Describing now the heating element, it preferably takes the form of a corrugated tube 16 extending centrally entirely through the still. At each end this heating element is rotatably mounted in the still by means of tongue and groove joint 17 comprising the members 18 secured to the heating tube and the member 19 secured to the still. This tongue and groove joint is the same at both ends of the heating element except that in connection with the movable end of the still, both the members 18 and 19 rotate while in the connection between the heating element'and the stationary portion of the still, that part of the joint connected to the stationary portion of the still is stationary. The heating element is provided with circumferentially extending gear 20 thatis drivenby gear 21 mounted on shaft 14 but between gears 20 and 21 is interposed an idler gear 22. The arrangement is such that the heating element will rotate in the opposite direction from the rotation of the movable part of the still.

Referring again to the stationary part of the still, oil is supplied to it by charging pump 23. The inlet side of thepump is connected by pipe 24 controlled by valve 25 to a suitable source of supply. The discharge side of the pump is connected to pipe 26 which leads to delivery pipe 27. A throttle valve 28 is interposed in line 26. The delivery pipe 27 extends through the still near the upper part of the latter and is provided at its lower side with a series of perforations or apertures 29. The inner end of the pipe 27 may be closed. The liquid residue is drawn ofi" from stationary part of the still through pipe 30 having throttle valve 31. The vapors pass out of this portion of the still through vapor line 32 provided with throttle valve 33. The upper end of the pipe 32 connects to the bottom of dephlegmator 34. This dephlegmator 34 has bafies 35 and at its lower end is provided with right angle partition member 36 and spaced cap 37. The arrangement is such that the reflux condensate will pass directly into the return pipe 38 which atits lower end is connected to the delivery pipe 2?. The last mentioned pipe is preferably of larger diameter than either the pipe 26 or 38. A throttle valve 39 may be interposed in pipe 38. The uncondensed vapors pass out of the dephlegmator through pipe 40 provided with throttle valve 41. This pipe 40 connects to condenser coil 42 which coil is seated in water condenser box 43. I The coil 42 is connected by pipe 44 to receiver 45. This receiver 45 is provided with liquid draw oil pipe 46 having throttle valve 47 and is also provided with gas outlet pipe 48 having throttle valve 49. Liquid level gauge 50 and pressure gauge 51 may also be rovided.

From the l'gregoing it will be clear that the heating element and also the main part pf the still may be constantly rotated and preferably in opposite directions. At the same time the charging line, vapor outlet pipe and liquid draw oil pipe are all connected to the stationary part of the still thus providing a more simple construction than if the entire still rotated.

We claim as our invention:

1. In an apparatus for treating oil, the combination with a still having a stationary portion and a rotating portion, means for feedin oil to the stationary portion of the 'still 0 a heating element extending through said still, means for rotating the movable portion of said still and said heating element 1n opposite directions, a vapor discharge from said still, a reflux condenser in communication therewith, means for returning condensate to the still, and means for dis charging residuum from the still.

2. An apparatus for treating oil, comprising astill, said still havinga. rotary porsealin with said rotary portion and a sup port for the still, an oil inlet leading into said still through the stationary end portion thereof, a heat conducting element passing throughthe still, means for rotatin said movable oil receiving portion of the sti l and the heat conducting element in opposite directions, a vapor dlscharge from the still, a reflux condenser receiving vapors from the still, and means for returning condensate to the still.

4. In an apparatus for treating oil, the combination with a still having a station- 'ary portion and a rotatable portion, of means for feeding oil to said stationary portion of the still, a heating element extending through said still, means for rotating the movable portion of the still and said heating element, a vapor discharge from said still connected to the stationary part thereof, anda separate dischar e for withdrawin residue from said still a so connected to sai stationary portion.
